1 Claim.

of which is adapted for attachment to the backframe. Between these two brackets I provicle a slotted link for the purpose of holding them, and

the frames to which they are respectively at- J:ached in the proper angular relationship when the. structure-is to be used as a davenport. One of the two brackets at each end of the bed davenport is connected by two nun-parallel links to a mountingmember adapted to be secured to the 20 stationary fram'e or base of the bed davenport.

The accompanying drawings illustrate my invention: Fig. 1 is a vertical.transverse section through a bed davenport, on the line II cf Fig. 6, the full line showing inclicating the position 25 of. the parts when the bed davenport is adjusted. to serve as a bed; Figs. 2 and 3 are fragmental views similar to Fig. l, but showing in Fig. 2 an intermediate position of adjustment and in Fig. 3 the adjustment 1:0 the davenport position; Fig. 4 is a view similar to Fig. 1 but showing the structure adjusted to serve as a davenport; Fig. 5 is a section on the line 5-5 of Fig. 4; ancl Fig. 6 is a top plan view of the structure adjusted to serve as a bed.

In a general way, the invention cf this application resembles that cf my prior Patent N0. 2,028426. granted January 21 1936, the chief difference between this application and the prior one being that the device of this application 1's primarily adapted for use in structures where the seat anal back frames are wood rather than cf steel, as in my prior patent.

The stationary part of my bed davenport comprises end frames I 0 interconnected by front and 45 rear rails I I and I2, and shaped to form the arms of the davenport. A panel I3 may extend between the side rails II and I2 at the bottom thereof to provicle with the side rails a box adapted 130 contain bedding.

An article cf the type With which this application is concerned includes relatively movable seat and back frames. The seat-frame I4 includes end members I5 anti the back-frame IG includes end members I'I. Conveniently, the two end members I5 ancl I'I at each end cf the bed davenfor attachment to the seat-frame and the other port are coplanar with each other and with a cross member I8 on the stationary frame or base- The mechanism employed to interconnect the seat ancl back frames at each end of the davenport includes two brackets 20 and 2I, conven- 5 iently cf sheet-m'etal anal adapted respectively for attachment to the seat-frame and back-frame, The two brackets 20 and 2I are provided with integral inwarclly extending arms 22 and 23 respectively which are pivctally interconnectecl, as by means 01 a holt 0r rivet 24. Preferably each of the brackets 20 anal 2I is located against the inside; face of its associatecl end member and is secured thereto as by means cf screws 25. Each brackeb,

has an ear 26 which is bent to overlie the upper surface o1? the associated end member to which it may be secured by a screw 27. Each of I;he brackets ancl 2I may also be provided a1: its inner edge with an outwardly extending ear 28 adapted to engage the inner end cf the end member I5 or I'I and to be secured thereto by screws 28'. (See Fig. 6.)

Pivoted 150 the inner face of each bracket 2I on the back-frame I provide a longitudinally slotted link 30 the slot in which receives a pin 3I to the associated bracket 20. Near the free end cf the link 30, its slot is provioled with an upwarcl extension 33 into which the pin 3I may ente1. When the pin 3I, lies Within the slot-extension 33 the seat-frame and back-frame relative angular relation shown in Figs. 2, 3, and 4; but upon raising the free end of the link 30150 free the pin 3I from the s1ot-extension 33 the seat-frame and back-frame may be moved into substantially co-planar relationship. 35

T0 each of the braekets 2I there are pivotally v connected two supporting links and II, the. opposite ends 01 such links being independently pivoted in spaced relation 130 a mounting member 42, such mounting members 42 being attached 40 to the cr0ss members I8 of the base of the bed davenport. The links 40 and 4I are cf such respective lengths, and their points of pivotal connection to the bracket 2I and the mounting member 42 are such that they guide the back-frame 45 I1 for movement between the generally upright; position shown in Fig. 4 and the horizontal position shown in Fig. 1. Conveniently, ohe ear 26 of the bracket 2I is provided with a projection which extends downwardly along the outer fa ee of the associated end member I'I and to which the upper end of the link 40 is pivotally connected; while the upper end cf the link 4I is connected 1:0 ehe bracket 2I by the pivot holt or pin 24. The

secured 25 are held in the upper end of the link 4I is offset inwardly to bring it into association with the arms 22 and 23.

II; Will be noted that when the back is in the upright position the lower end of the back-frame I'I is near the rear of the base, while in the horizontal position it is near the longitudinal center line of the base. 'Ihe precise amount of inward movement cf the lower end of the back-frame I'I, as that frame moves from its vertical to its horizontal position, will depend largely upon the relative widths of the seat-frame and back-frame, the object being to have the seat-frame and backframe overhang the sides of the base by approximately equal distances When the structure is adjusted to provide a bed.

When the structure is to be used as a davenport, the parts occupy the positions shown in Figs. 3 4, and 5. In this condition, the pin 3l on each bracket 20 is received in the slot-extension 33 of the associated link 30, and the backframe I'I and seat-frame I6 are thereby supported in fixed relative angular position, the force of gravity acting upon the link 30 serving to hold it downward and thus to maintain the engagement between the pin 31 and the slot-extension 33. The links 46 and 4I occupy nearly vertical positions and thus serve as struts supporting the rear side of the seat-frame I4, the front side of the seat-frame being supported by the front rail II of the base on which it rests.

When it is desired to convert the davenport into a bed, the front edge of the seat-frame I4 is raised, thus elevating the seat-frame and lowering the back-frame. This movement is continued until the back-Hanne engages the rear longitudinal rail I2 of the base, as indicated in Fig. l, the seat-frame then occupying the dotted-line posi tion shown in Fig. l. T0 complete the adjustment, the links 30 are raised to disengage the pins 3I from the slot-extensions 33, whereupon the seat-frame may be lowered to the full-line position shown in Flg. 1 where it again receives support from the front rail I I.

Conveniently, mechanism operable from the 'f1'0nt of the davenport is provided for raising both links to disengage the pins 3I from the slot-ex tensions 33. This mechanism may, as in my copending application, take the form of a rockshaft 50 which extends longitudinally of the seatframe I4 near the rear edge thereof. At its ends, the shaft 50 is ofiset to provide cranks 5I which engage the lower surfaces cf the links 30. At an intermediate point, the shaft 59 is provided with a third ofiset forming a crank 52 which is connected t0 an operating rod. 53 that extends forwardly across the seat-frame I4 to have its front end slidably received in a suitable guide bracket 54. 'Ihe operating rod 53 may be provided with a handle 55 of any convenient construction.

The normal positions of the cranks 5I are shown in Figs. l, 2, 3, and 4. As is clear from Figs. 2 and 3 when the pin 3I is received in the slot-extension 33 of the link 3D, the cranks 5I are out of engagement with the links, thus permitting the links to drop under the influence oi gravity. When with the seat-frame occupying the dottedline position shown in Fig. 1, the operating rod 53 is moved forwardly, the cranks 5I Will be raised to lift the free ends of the links 30, as indicated in dotted-lines in Fig. 2. 'I'his movernent of the links frees the pin 3I from the slot-extension 33 and permits the seat-frame to be lowered. As the seat-frame is lowered, the lower surface of each link 30 forces the cranks 5I to assume their normal position; so that when the seat-frame is again raised the cranks Will not prevent the links from dropping to engage the slot-extensions 33 with the pins 3I.

'Ihe pivotally interconnected brackets 20 and 21 at each end of the davenport, together with their associated adjusting link 3IZI, supporting links 40 and 4 I, and mounting member 42, form a unitary sub-assembly which, in practice, is manufactured complete as such, the seat and back frames of the davenport being later mounted in such subassembly. The ears 2I and 28 on the brackets locate the seat and back frames in definite positions in the brackets, and the only part 0f the subassembly whose point of attachment to the wooden parts cf the complete structure must be measured is the mounting member 42.

I claim as my invention:

In a bed davenport, a base, a seat frame having end members, a back frame having end members, a pair of brackets respectively associated with the end members of said seat and back frames at each end of such frames, each of said brackets being secured against the inner face cf its associated end member, said brackets having integral arms approximately coplanar respectively with the brackets, said arms overlapping each other, one of said brackets being provided with an ear embracing one edge of the end member associated with that bracket, a mounting member attached to said base a supporting link pivotally connected to said ear and 130 said mounting mernleer, a second supporting link disposed outwardly beyond said end membe1s and having its lowe1 end pivotally attached to said mounting member and its upper end ofiset inwardly into association with said arms, and a pivot pin pivotally interconnecting said arms and said second supporting link.
